They're completely orthogonal concepts, merged in the past due to
convenience and ease of implementing it in the old #ifdef hell renderer.
Especially after the CMS stuff was generalized by 634b4a, this was a
trivial change to implement and also means color management will be much
higher quality when enabled with vo=opengl (which had quantization
issues in the past due to the 8 bit FBO format and upscaling), since it
can be done in a single pass now.
While all functions of input_ctx are inherently thread-safe, access to
the _inputContext field itself is not. It could be unset any time by
cocoa_set_input_context(). So even trivial input_ctx calls must be under
a lock, so that the input_ctx can not be destroyed while the function
call is "starting". (Even a function call in progress wouldn't be fine,
because mp_input_uninit() requires the caller to "own" the object, i.e.
no other threads can access it at this point.)
For certain reasons, we allow adding external tracks even before the
main file is loaded. This somewhat breaks in old assumption, which uses
mpctx->num_sources to determine whether a command can be applied in the
current state. Use the newer playback_initialized instead, which is a
much better choice for this purpose.
The previous commit removed this. Although mp_switch_track() can now be
called in all situations, we still don't want it to be called here.
Setting a track property while no file is loaded would simply deselect
the track instead of setting the underlying option to the requested
value.
Likewise, if the "cycle" command (M_PROPERTY_SWITCH) is used, don't just
deselect the track.
Adding an external audio track before loading the main file didn't work
right. For one, mp_switch_track() assumes it is called after the main
file is loaded. (The difference is that decoders are only initialized
once the main file is loaded, and we avoid doing this before that for
whatever reason.)
To avoid further messiness, just allow mp_switch_track() to be called at
any time. Also make it do what mp_mark_user_track_selection() did, since
the latter requires current_track to be set. (One could probably simply
allow current_track to be set at this point, but it'd interfere with
default track selection anyway and thus would be pointless.)
Fixes#1984.
Wnile it seems quite logical to me that commands use _ as word
separator, while properties use -, I can't really explain the
difference, and it tends to confuse users as well. So always
prefer - as separator for everything.
Using _ still works, and will probably forever. Not doing so would
probably create too much chaos and confusion.
Now it simply changes the options, i.e. what will be requested, instead
of returning M_PROPERTY_UNAVAILABLE.
This is another minor step towards unifying options and properties.
Still a bit weird: it will always return "no" if no file is loaded, and
disregards the option value.
Also replace their implementation with the recently introduced
properties. One significant difference is that audio-channels using OSD
formatting does not print the channel layout. The user can just use the
replacement property instead.
This brings the volume control closer to what is percepted as linear
volume change.
Adjust the --softvol-max default to roughly the old maximum (roughly
doubles the gain).
Now --volume takes an absolute volume, meaning it doesn't depend on
--softvol-max. 0 is still silence, and 100 now always means unchanged
volume. The OSD and the "volume" property are changed accordingly.
Also raise the minimum value of --softvol-max. A value below 100 makes
no sense and breaks the OSD.
Adding a "yes" choice makes the option parser consider this option as a
multi-state flag option, and without argument "yes" is implicitly
selected. "yes" is made an alias for "inf", so it will loop infinitely.
As a negative side effect, the old syntax "-loop inf" does not work
anymore. Since this is ambiguous, the option parser prefers interpreting
the "inf" as filename.
Fixes#1970.
This was called for formal reasons at best. The way it does this is
somewhat dangerous, because if libmpv is unloaded as DLL, this would
attempt to call a dangling function pointer.
(No, we don't want an extra DllMain entrypoint just for win32.)
